Gamespot have a nice write up of their experiences playing Micro Machines v4 at E3.

The PSP version is exactly the same as the PS2 version, with more than 50 tracks, 25 weapons/power-ups, and 700 vehicles. Races can accommodate up to four people, with artificial intelligence opponents in single-player mode or real players in wireless multiplayer modes.

Although the Micro Machines series gets criticised from some quarters for its pretty basic gameplay, its a game I’ve always enjoyed playing. Must be the over grown kid in me or something.

Hopefully the PSP version of this game will live upto expectations, and judging by the build version that Gamespot enjoyed playing, it should meet its June release date.
